Mr 'present invention liao .rotoroooo 'to a* box' or lalio'lder .for Aoil stones, such as are ooiomonlr" ,omrloyod lor Carpenters loable@ makers and l.the i lilo for Sharpening ods@ reels?.

Anf object of the invention is the provr sion of a box for .this .purpose having a cover 'in v,the `nature iof` anv oil well ,or receptacle eorml'li olooodr by a' Spring ofluonood valve 'tvliiichflatter opened pressure against andthefexure ofthe top vofthe cover, so @alla sulfi'oioet quantity-of oil .may bo oon- Y-oiioiltly oldo tho otono and tho .employ ment of anx oil canfor thisfpurpose entirely overcome. 4 f

' ustill further object is the provision of an oilfstone box in which vthe stone is firmly held'but is susceptible to swinging and tilting laterally so that either of faces may be arranged in grinding position. c

With the above broadly stated objects in view, and many 'others which will present themselves as the nature of the invention is better understood, the improvement further resides in certain other novel features of construction, combination and operative association of parts, a satisfactory embodi ment of which is illustrated by the accompanying drawings.

In the drawings:

Figure 1 is an approximately central longitudinal sectional view through my `improvement, the oil stone being in elevation.

Figure 2 is a sectional view approximately on the line 2 2 of Figure 1.

Figure 3 is a detail sectional view approximately on the line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional view approximately on the line 4 4 of Figure 2.

Mechanics having use for oil stonesfor sharpening edge tools are well acquainted with the inconvenience of applying oil in the usual method. In the first place, the oil can is seldom conveniently located, and in the second place the cover for the'box seldom excludes dust from the stone and in the third place great inconvenience is occasioned in removing the stone from the pocket in the box so that the grinding face thereof can be reversed. My improvementv aims to obviate allV of these inconveniences. The base or box proper'may be, and preferably is constructed of wood. This base is indicated in the drawings by the numeral 1.

3- The. .odos-and 'ends of tho base, .opposite the end of fthefpoclret lare channeledor cntovay 4to Provide a continuous horizontal lodge-4 'and a `ooofilnlflms opstanding Hang@ 54 l? is, of ooorso, t.o bo'uodoretood that lthe basehorbox is of rectangular formation.

On one of the inner `faces of the end flange 5 ,there is ournaled vin'snitable ,bearings rod or bar 6.y Centrally connected to bar there is a pivot member 7. 'Ihe .pivot has both of its ends headed and 'vis'qpreferfably 'Surrounded by a Skov@ 8 laai'paes e yokeflike clamp, 9 from the bar ,or "p latefl. The yokedike clamp kp9 .is connected to the vpivotk?, `and the sprino arms 10,'of2'tlie Yyoke may be received in y epresignis Y-ll'fintl'ie sides and one Aend of the oil stone. 'flowever, this is not an absolute requirement, as one end of the oil stone may be fully received within the yoke and held therein in frietional engagement with the arms 10 at the sides of `the said stone. The opposite yend Hange of the box 1 may have its inner face out at a slight angleso that the stone may be swung out of its pocket 2 about the axis of the bar 6 and then turned on the ,pivot 7 to bring the second face of the stone the cover 12, at a suitable distance from the top thereof, there is a partition 14. By reference to Figures 1 and 2 of the drawings, it will be noted thatthe partition is -arranged in the cover a suitable distance above the stone 3, so that the resiliency of the lower sides and ends of the cover is not impaired and also that the said partition doesnot Contact with the stone.

The partition may be of any' desired `material and the same is, on its outer face,

centrally enlarged and provided with a threaded opening. In this opening there is screwed a capy nut 15. nut has a central opening therethrough for the reception of the stem 16 of a valve 17.

The top of the cap;

The valve, on its inner face, has a comprestop of the cap to Hex the saine inwardly, a f like pressure 'will' be exerted upon the head 19, which will niove the stein 16 tonnseattheA valve 17, andthi'is eini't a sufficient quantity of oii, (which, it should rbe stated, is received in the compartment between the top and the partition 14 of the cover), to allow adeterniined quantity of such oil fiowing onto the stone. Thus the stone is oiled before the cap-is removed from the box, The supply of the oil is replenished by opening the valve and employing the cap nut15 as a funnel to allowthe said oil te pass through the rather large opening kin the cap nut that provides the guide" for the stein 1G.

The simplicity of iny construction and the advantages thereof, will it is believed, be

iifanemy perfectly apparent to those skilled inthe art to which this invention relates, when the foregoing description has been carefully read in connection with the accompanying drawings.

It is, of course, to be understood thatdo not wish to be restricted to the precise details herein set forth and n'iay" inake such changes therefrom as fairly` fall within the scope of what I claiin.

` Having described the invention, I claiin :-Y

rfhe combination with an oil stone boXY and an oil stone therein, of a yoke-like spring clainp whose arins i'rictionally engage with the sides of the oilstone, a central pivot eztendingfiointhe clainp and abar having its ends retat'zibly li'ouriialed in bearings on one of theiiiner ends of the box and to which the pivot is connected.v the wall ofthebOX' opposite said bar being cut awayfat'an angle te perl iit the swinging of the stone out of the boit about the haras anfaxis andits swivelling about the central pivot to Vreversely posi# tion the stone. v

In testimony whereof I, affix my signature.
